When Winston was 2 he went in for his routine visit where they took labs. His creatine levels were on the high end. The vet wanted to do this whole work up. I spoke with a friend who has used Honest Kitchen and she recommended I tried out the Keen (lower protein) dehydrated food and see if that lowers his levels any. The vet flat out told me that it wasn't going to help any. I had went and got a second opinion and kept giving him the Keen mixed in with kibble and his levels have improved. I'm so happy to have found a product that has helped my baby boy.
